There have been 76 breaches of quarantine conditions in the last three months, despite concerted efforts from officials to keep those in managed isolation separate.
A spokesperson for Managed Isolation and Quarantine told Newshub all facilities operate under COVID-19 alert level 4 conditions - but that doesn't mean breaches don't occur.
Since August 27 facilities have recorded 76 incidents of mixing and mingling, or failure to wear personal protective equipment (PPE).
"Unauthorised mingling does occur in managed isolation facilities. This includes unintended breaches as well as deliberate incidents, as many breaches are accidental," the spokesperson said in a statement.
Some of these accidental breaches include staff using lifts guests have been in recently, not wearing masks, or children from different bubbles playing together in a corridor.
"Minor breaches are responded to with an education approach and/or a warning. We do not rely exclusively on CCTV images alone, as on-site staff are observing constantly in the facilities."
Two breaches were in quarantine facilities and 11 were in facilities that had a quarantine wing as well as an isolation wing, reported the New Zealand Herald.
Most of the incidents, 56, involved guests, but nine involved workers and three were by security guards.
It is unclear whether staff and security will face penalties.
The Ministry of Business and Innovation, which is responsible for the managed isolation facilities, has stressed that the majority of people in managed isolation are well-behaved.
"To date, over 75,000 people have completed their managed isolation stay safely, and have returned to their loved ones and friends."
